To all yw/wm t may. concer/1i:

Be it known that JAY Oris VHEELOCK,

a citizen of the United States, and resident of Louis, State ofMissouri, have invented certain new and useful inprovements inPhotographic Devices, of which the following is a specifica-tioncontaining a full, clear, and exact description, reference being had tothe accompanying drawings, forming apart hereof.

The objects of my invention are to construct a photographic device whichmay be used in a studio or for home portraiture for producing variouseifects to be used as a background for pictures, etc. The variouseffects that may be. produced are as follows: a window with any desiredyiew discernible therethrough, the' window and view bein(r made asclearly deh'ned or as indefib .v

nite as the necessities of the case may require; any scenery screen canhe `-nade to appear realistic by means of the devies g a darksurfaceinade to appear light and a light surface made to appear dark.

7 ith the above and other objects in View, my invention has relation tocertain novel features of construction and operation, amples of whichare described in the following specification and illustrated in theaccompanying d awings in which- Figure 1 is a perspective View of aconventional window sash, sill, etc. with my device attached. Fig. 2 isa fragment-al sectional elevation taken at 2 2 Fig. 1. Fig. 3 is asectional elevation of one of the rods used in my device.

In the drawings numeral at designates a sill, 5, a head, 6 the insidefacing, 7, the upper sash, and S, the lower sash, and 9 and 10 thelights of glass and 11, the jamb. and 12 the stops of a conventionalwindow easement.

My device consists of an extensible rod composed of two parts 13 and 14with a screw plug and its point 15 at one extremity land the point 15 atthe other together with a set screw 16. By means of this structure,

thelength of the rod may be changed at will by loosening the set screw16. The points -15 and 15 enable the rod to be held in a window frame atany point as indicated in Fig. 1. In the form shown in the drawings twolsuch rods are required, although oneor more may be used. To the one isattached a translucent screen 17, (made of porous cloth or other similarmaterial) on which is painted, stcnciled or otherwise ymarked, theconfiguration of a window, etc.;

to the other is attached a translucent screen 18 on which is painted,stenciled or otherwise marked the configuration of some desired scenery.

-Oii Fig. 1, a. French window 17a is shown on screen 17, partly brokenaway, disclosing the scenery 18u on screen 18 in the rear. By means ofthe extensible rods, these screens may be used on windows of variousdimensions. These screens may be used with any source of light, eithernatural or artificial, and may be used without a window casing, etc., inwhich case, the imprint of the entire configuration of a window andeasement is made on the scren 17. Screens l 17 and 1S may both bemounted on the same rod; 18 always being placed in the rear of 17 z. c.,to say closest to the source of light; oi' in a modified form only onescreen may be used having the configuration of a window `imprinted onone side and of scenery on the other.

The screens may also be positioned adjacent a wall from which reflectedlight is emitted ;A thereby darkening or brighteniug the appearance ofthe wall depending on the color and consistency of the translucentscreens used.

lVhat l claim .is-

1. ln combination with a s urce of light, a translucent screen bearing aphotographic background mounted in advance of said source of light, asecond translucent screenbearing a background for photographicassociation with the iirst mentioned background in advance of the firstscreen and means ivliereby the Screens may be relatively spaced togradate 'the Visibility of the first `mentioned background through 'thesecond screen.

Q. A. photographic backo'round appara' tus, comprising a source oflight, a pair. of translucent screens each bearing 'a differentbackground, the one risible through the other and means whereby thescreens may be diiferently spaced relative to each other and to thesource of light, whereby to gradate the visibility of the rearlnostbackground through the foremost screen and gradate the volume of lightthrough the two screens.
